There is also a Log in option in the navigation, and a "Skip to content" link for accessibility.

About

The About section explains the purpose of the site and its author. TNL.net has explored the intersection of technology and society since 1994, according to the site's own introduction. Tristan Louis is described as the co-founder of 6 startups, former CIO of HSBC, and former head of mobile and Internet for Deutsche Bank; he is now CEO of Casebook.

Blog

The blog is the longest-running part of the site. It has published tech industry analysis for roughly three decades and was previously distributed as the TNL.net newsletter. Recent posts listed on the homepage include "A 250-Year-Old Matter of Punctuation," "It's All About Information," and "The Long Fight." You can follow new posts via the site's RSS feed.

Search

If you can't find something by browsing, the Search section is designed to help you locate it quickly. Use it when you know the topic but not the section.

Subscribe

The Subscribe section takes an email address and signs you up for updates. Enter your email in the field and submit to subscribe.

How to contact Tristan Louis

The Contact section is the central place for reaching him. Beyond that page, the site lists several direct channels:

• Contact page — the primary entry point for inquiries
• LinkedIn — Tristan Louis's professional profile
• Mastodon — his profile on the federated social network
• Bluesky — his profile on the Bluesky network
• RSS feed — for following the blog
• Phone — +1 646 321 7488
• Mail — 380 Lenox Avenue, PH12F, New York, NY 10027

Which channel to use

• For speaking, advisory, or business inquiries, start with the contact page so your message reaches the right place.
• For professional networking, use LinkedIn.

• For following new writing, subscribe by email or add the RSS feed to your reader.

What Tristan Louis does, based on the site

Knowing his roles helps you route your request correctly:

• Advisor — advises corporations and governments on digital transformation
• Speaker — available to keynote, moderate, or host events
• Writer — published by The New York Times, Forbes, Business Insider, IEEE Spectrum, and others

The site also displays endorsements from figures at organizations including Pearson, Chiba Institute of Technology, Tom's Hardware, MSG Securities, EFF, and SSAB, under the heading "Trusted by iconic brands."

Common points to check before reaching out

• Use the contact page first for anything formal. The phone number and mailing address are listed, but the contact page is the intended channel for inquiries.
• Match the channel to the purpose. A speaking request and a casual comment belong in different places.
• Check the blog before asking about a topic. With three decades of posts, the Search section may already have an answer.
• Note the site's scope. TNL.net is a personal site, so it reflects Tristan Louis's own analysis rather than a company support desk.
